nah I've used it on model rocket engines :edit: I've started work on the calculations

I'm not saying its easy, but if I can get the temp within 300 degrees of the melting temp of the extrusion material, I can use gasket sealant used in cars to cover the inside of the pulse jet, maybe more if I can find a better insulator, I'm keeping flight times low for this exact reason, eventually it will melt, I just want to make it usable before it does

Valveless, I think I can tweak the mixture to reduce temp

Hand tools, drill, hammer, and the likes. I can get to a 3d printer at school. The plastic would be easier to manufacture labor-wise, but it would be a little more complex to insulate from the heat

So I was thinking (in the middle of german class), somehow I got from how much I wanted out of there to pulsejets. From there I started to go through ideas of possibly making my own pulsejet, eventually leading me to the question: can I 3d print a functional, and integratable pulsejet for R/C models, etc? The short answer is sort of, yes. The biggest problem with the entire concept is cooling it. I'm saying that a 5 minute run time with throttle to the firewall, preferably 10 at 3/4. SO, after thats out of the way, lets get "technical". PROBLEM 1! Cooling - Pulsejets get hot, like, really hot, so I need to figure out how to insulate the plastic from the extreme temperatures from the combustion PROBLEM 2! Pulsejets are weird, they "pulse" the fuel flow to allow the suction/blow of a normal running pulsejet, I want to keep the jet simple, I.E. no computertrons beep-bopping around with timers, mainly because I cant code. Current progress is stuck at how to insulate the 3d-printed structure from the heat, however I'm formulating an idea, and I'm not great at cad.

Lookin good, and getting even closer, its looking like the flame regresses into the chamber once good combustion starts

Will I return? Who knows

Another happy landing

Its progress! (and getting closer)

Eh I'm regretting not studying last night, had a small quiz

this tbh

That's funny @Lo Var Lachlandd Ok I give up trying to delete that d, stupid autocorrect. Anyways, my girlfriend has a very similar style

the mixing of the fuel will be sub optimal, at best

uuuuuuuuuuh THE MITOCHONDRIA IS THE POWERHOUSE OF THE CELL

excellent chloroplasts

Hahahahahahahahah I had to listen to it for two weeks. Straight. Never again.

nice to see progress!

that interstellar asteroid

slowly add in mods till its back? one by one

I accept that challenge

sorta dropped phone, impressive as to how much it cracked

so you're saying taking a broom (?) to him is fine, or a bat

However effective, (at least I believe) there should be some chivalry, obviously hes not putting life in danger, not yet at least (he would have a knife), and being kicked in the balls is probably the worst thing you can really do pain wise. Kicking out the opponents knees would do the same thing, and not like, ensure they never reproduce. If its a life or death scenario, sure, but hes not going to do anything of the sort in full view of staff.

AWESOME Never seen a exhaust plume like that though
